My husband worked half days through his treatment. After treatment he missed some days. His employer was NOT as nice. He was treated very poorly after he was done with treatment. They needed someone more dependable, he would have to call in sick some days. He had over 1500 hours of sick leave accumulated prior to his diagnosis and had 30 years in. To say it devasted him emotionally is an understatement. He still hasn't recovered from it. You are a wonderful employer and caring person. I know that having to go to work helped Bob through his treatment and I am sure it will help Ellen plus the fact she has job security.
